Hi Nate, I am in the middle of rebuilding my 2QM15 which came with my C&C 29 mk1. I disagree that the engine needs to be pulled to get out the transmission. You can pull the transmission without pulling the engine. You will be surprised, but the 2QM15 transmission weighs only about 20lbs. But since the rear motor mounts bolt to the transmission, you will have to support the rear of the engine. This can be done by either stacking boards under the oil pan (use wide boards) and/or using a block and tackle to lift from your boom. Connect the tackle to the middle of the boom with some good rope, then bring other end of the tackle into the cabin/engine compartment connecting it to the rear engine lift ring which is on the rear of the cylinder head. It easier than it sounds, and it should be a simple job. I would leave the engine mounts connected to the transmission unbolting them from the stringers. That way you do not change the mount adjustments keeping your engine aligned when returned.
I pulled my engine out single-handedly using my boom, main sheet, and vang block and tackle. I first pulled the engine onto plywood into the cabin. I then removed the transmission thinking it would reduce weight, but was surprised by how light it was. Using both blocks systems, I lifted the engine up, out, and swung it over and down onto the dock next to my boat. Using a 2X4 looped to the engine lift rings, another person and I walked the engine off the docks. The 2QM15 total weight is about 320lbs. - Paul E. s/v Johanna Rose Carrabelle, FL On Aug 1, 2012, at 12:00 PM, cnc-list-requ...@cnc-list.com wrote: > Date: Wed, 1 Aug 2012 14:37:20 +0000 > From: Nate Flesness <n...@isis.org> > To: "cnc-list@cnc-list.com" <cnc-list@cnc-list.com> > Subject: Re: Stus-List Transmission Fluid leak (Yanmar 2qm15) > Message-ID: > > <3d3ec17e62a20f4c8771d26b7c51385311453...@bl2prd0510mb385.namprd05.prod.outlook.com> > > Content-Type: text/plain; charset="utf-8" > > After a couple of years of small drips, my 32 year old Yanmar started leaking > transmission fluid at an ounce an hour while motoring last weekend. > Probably from the forward seal ? where it meets the engine.
